Ke Jingping instructed Ling Han that the mole’s life must end today. Wen Yeming led agents to the room where the military command was being monitored. She discovered that the house had been rented the previous year by Niu Erhong. Ke Jingping asked about the occupant, but Wen Yeming reported they hadn’t captured anyone. Ling Han stated that the individual wasn’t important, but the mole would surely strike again. Ke Jingping inquired about the commander’s arrival, and they assured him he would be there soon. Ke Jingping anticipated the mole would take action during the upcoming events, urging everyone to be vigilant. Yun Hongshen wrote the intelligence on a piece of paper, photographed it, and then burned the paper.
Wen Yeming opened a cabinet and placed the photo inside. Just as she closed it, someone shouted “Fire!” Everyone rushed to the burning archive room. Meanwhile, someone entered the meeting room, attempting to retrieve the photo Wen Yeming had just hidden. Ling Han and his men walked in, catching the culprit red-handed. It was Li Liang. Li Liang told Ling Han not to look at him like that, claiming he was merely following Deputy Station Chief Zhu’s orders. Elsewhere, Ke Jingping and Deputy Station Chief Zhu were speaking with Deputy Officer Chen. Ling Han approached Ke Jingping and discreetly informed him of the situation. Ke Jingping glanced incredulously at Deputy Station Chief Zhu beside him, then left with Ling Han.
Ling Han admitted that Li Liang didn’t fit his image of the mole, but it was possible he was pretending. He found Deputy Station Chief Zhu, on the other hand, to be a more likely suspect. Ke Jingping cautioned him against jumping to conclusions, suggesting they wait for Wen Yeming and Yun Hongshen to search Li Liang’s house. At Li Liang’s house, Wen Yeming discovered numerous photos of him accepting bribes with the deputy station chief. She was outraged that someone would engage in corruption during a national crisis. Yun Hongshen remarked that it wasn’t surprising, suggesting even Ke Jingping might be taking bribes. Wen Yeming angrily defended her teacher, highlighting his dedication to the revolution, his lack of marriage and personal property, and his austere lifestyle of living in the office.
Yun Hongshen, realizing Ke Jingping was Wen Yeming’s teacher, quickly apologized for his remark. He urged her to calm down and suggested she hand the evidence over to Ke Jingping, as it wouldn’t be admissible in court. Wen Yeming and Yun Hongshen returned to the military command and presented the evidence to Ke Jingping. Ke Jingping summoned everyone and had Li Liang brought in. Li Liang continued to insist he was following Deputy Station Chief Zhu’s instructions. Ke Jingping demanded evidence, but Li Liang couldn’t provide any. Ke Jingping ordered Deputy Station Chief Zhu to deal with him.
Ke Jingping called Deputy Station Chief Zhu to his office and discussed the next steps. He cryptically told him that as long as their goals aligned, he would turn a blind eye. Back home, Yun Hongshen found Yun Hongqi waiting for him. Yun Hongqi warned him about the dangers of the military command, a place where killing was commonplace. He expressed concern for Yun Hongshen’s safety, but Yun Hongshen insisted he had to be there. Yun Hongqi didn’t understand why, but he knew it was what Yun Muzhi wanted. Yun Hongshen declared he was prepared to die, prompting Yun Hongqi to threaten telling Yang Ziming.
Yun Hongshen urged him not to involve Yang Ziming and told him to forget about their encounter at the temple. Ling Han remained unconvinced that Li Liang was the mole, believing someone else was responsible. Ke Jingping visited his secret base and found Ling Han still investigating the mole. He asked Ling Han if he would persist despite any opposition. Ling Han confirmed his determination, and Ke Jingping patted his shoulder in support. Yun Hongshen visited the children’s welfare home, where he encountered Wen Yeming. She accused him of following her. Yun Hongshen explained he was there to deliver stickers to the children. As they chatted, Yun Hongshen asked if her family approved of her joining the military command. Wen Yeming revealed she had no family and correctly guessed that Yun Hongqi disapproved of Yun Hongshen’s decision.
